poor electrical conductivity and electronegativities greater than 1.7 7. What is the number of electrons in an atom that has 20 protons and 17 neutrons? 1. 37 (2.

What element has 20 neutrons and mass of 35?

An atom of chlorine-35 contains 18 neutrons (17 protons + 18 neutrons = 35 particles in the nucleus) while an atom of chlorine-37 contains 20 neutrons (17 protons + 20 neutrons = 37 particles in the nucleus). Adding or removing a neutron from an atom’s nucleus creates isotopes of a particular element.

### What isotope has 17 protons and 17 neutrons?

isotope Cl-37
Statement 1 : The isotope Cl-37 has 17 protons, 17 neutrons, and 17 electrons.

How many neutrons are in 35 17 CI?

18
A chlorine nucleus will contain: Number of protons Z = 17. Number of protons + neutrons A = 35. Number of neutrons N = 35 – 17 = 18.

## Which element has 16 neutrons?

phosphorus
if you look at the periodic table, phosphorus has 15 electrons and protons, and 16 neutrons.

Which particle has the least mass?

The mass of an electron is negligible as compared to that of neutrons and protons and thus the atomic mass is given as the sum of the mass of protons and neutrons.

### What is the atomic mass equal to?

The mass of an atom in AMU is roughly equal to the sum of the number of protons and neutrons in the nucleus. The AMU is used to express the relative masses of, and thereby differentiate between, various isotopes of elements.

What is the atomic mass number equal to?

The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in any atom is its mass number minus its atomic number.

## What has 17 protons and 18 neutrons?

Chlorine-35
Chlorine-35 has 17 protons and 18 neutrons. It’s considered a stable isotope and is the most abundant isotope of chlorine, with approximately 76%…

What has 4 protons and 3 neutrons?

Lithium
Lithium, for example has three protons and four neutrons, leaving it with a mass number of 7.

### What element has 17 protons and 18 neutrons?

chlorine atom
Every chlorine atom has 17 protons in its nucleus. Not all atoms of chlorine have the same number of neutrons, however. Some atoms of chlorine have 18 neutrons in their nuclei.

What is the difference between CL 35 and CL 37 which has more protons which has more neutrons?

There are three isotopes of chlorine that differ from each other according to the number of neutrons in their atomic nucleus. The key difference between chlorine 35 and 37 is that chlorine 35 has 18 neutrons per atomic nuclei, whereas chlorine 37 has 20 neutrons per atomic nuclei.

## What element has 17 protons?
